Survival of Patients With Angina Pectoris Undergoing Percutaneous Coronary Intervention With Intracoronary Pressure Wire Guidance.

In this observational study, the use of FFR was associated with a lower risk of long-term mortality, ST, and restenosis in patients undergoing PCI for stable angina pectoris. This study supports the current European and American guidelines for the use of FFR during PCI and shows that intracoronary pressure wire guidance confers prognostic benefit in patients with stable angina pectoris.
